There is a consistently high level of public support across nations for a global carbon tax if the tax policy is carefully designed, according to a survey of people in the United States, India, the United Kingdom, South Africa, and Australia. The research was published in Nature. "Imposing a cost on carbon is the most economically efficient way to reduce greenhouse gas emissions," said economist and lead author Stefano Carattini, an assistant professor in Georgia State University's Andrew Young School of Policy Studies. "Our research shows that a system of harmonized carbon taxes, in which countries agree on the tax rate but maintain control over tax revenues, would be the easiest way to achieve a global carbon price." In the survey, 5,000 respondents from the five countries were asked their opinions on different carbon tax designs and whether they would support a carbon tax to be implemented in their country in 2020, if this was also done in all other countries. The majority of the respondents--from 60 percent in the United States to above 80 percent in India--supported carbon taxes in scenarios where revenues are given back to people or spent on climate projects. "The high level of public support suggests a major rethinking of how we approach carbon taxes and international cooperation," said co-author Steffen Kallbekken, research director at the CICERO Center for International Climate Research in Oslo, Norway. Carattini, Kallbekken and co-author Anton Orlov, a senior researcher at CICERO, simulated the effects of the carbon tax in an[…] -
Battery Boom Aids Climate Change Battle

The fastest-expanding industrial sector on the planet is now electricity storage − a battery boom which heralds an end to the need for fossil fuels. Billions of dollars are being invested worldwide in the developing battery boom, involving research into storage techniques to use the growing surpluses of cheap renewable energy now becoming available. Recent developments in batteries are set to sweep aside the old arguments about renewables being intermittent, dismissing any need to continue building nuclear power plants and burning fossil fuels to act as a back-up when the wind does not blow, or the sun does not shine. Batteries as large as the average family house and controlled by digital technology are being positioned across electricity networks. They are being charged when electricity is in surplus and therefore cheap, and the power they store is resold to the grid at a higher price during peak periods. According to Bloomberg, around US$600 billion will be invested in large-scale batteries over the next 20 years to provide back-up to the grid and power for the expected boom in electric cars. The cost of batteries is also expected to fall by 50% in the next decade, following the same pattern as the drop in cost of solar panels.“The generally-held belief that there was no way to store electricity has been disproved. The battery boom means it is now just a question of finding the easiest and most economic way of doing it”Read more at Battery Boom Aids Climate Change Battle -
Pentagon Confirms Climate Change Is a National Security Threat, Contradicting Trump

The military walks a fine line between the White House’s official climate denialism and the stark realities of a warming planet. More than a year after President Donald Trump nixed climate change from his administration’s list of national security threats, the Pentagon has released an alarming report detailing how dozens of U.S. military bases are already threatened by rising seas, drought, and wildfire. “The effects of a changing climate are a national security issue with potential impacts to Department of Defense missions, operational plans, and installations,” states the 22-page document, which was published Thursday. The congressionally mandated analysis looked at a total of 79 military installations around the country. The Defense Department found that 53 sites are currently vulnerable to repeat flooding. Langley Air Force Base in Virginia, for example, has experienced 14 inches of sea level rise since 1930. Additionally, more than half of the 79 bases are at risk from drought, while nearly half are vulnerable to wildfire. These climate impacts are expected to pose a risk to several other installations over the next two decades, and the report notes that “projected changes will likely be more pronounced at the mid-century mark” if climate adaptation measures are not taken. While the report is a clear recognition of the immediate threat that climate change poses to the nation’s military infrastructure, it makes no mention of the greenhouse gas emissions driving the crisis. It also doesn’t mention some of the most recent climate-related devastation to military bases, including the estimated[…] -

Speaking to the press at the North American International Auto Show in Detroit this week, Jim Farley, Ford’s president of global markets, said, “Here’s what’s going to happen next to future-proof that global juggernaut of commercial vehicles. We’re going to be electrifying the F-Series, both battery-electric and hybrid. And we’re doing the same for Transit. No transition is perfect. In a way, we had the advantage of watching what happened the first time around. (Customers) want really good stuff,” he added in an obvious reference to Tesla and Elon Musk.

Stop & Shop is partnering with Robomart to launch driverless grocery vehicle service in the Greater Boston area beginning in Spring 2019. The vehicles will bring a selection of Stop & Shop produce as well as meal kits and convenience items directly to consumers. Stop & Shop customers in the Boston area can summon a Robomart vehicle with a smartphone app. Upon the Robomart vehicle’s arrival, customers head outside, unlock the vehicle’s doors, then personally select the fruits, vegetables, and other products they would like to purchase. When finished shopping, they just close the doors and send the vehicle on its way. The vehicles’ RFID and computer vision technology automatically records what customers select to provide a checkout-free experience, and receipts are e-mailed within seconds.For decades, consumers had the convenience of their local greengrocer and milkman coming door to door, and we believe that by leveraging driverless technology we can recreate that level of convenience and accessibility. We’re extremely excited to bring our vision to life with Stop & Shop, one of the most pioneering and forward-thinking grocery chains in the world. —Ali Ahmed, Founder & CEO of RobomartAll Robomart vehicles are autonomous, electric, and will be remotely piloted from a Robomart facility. Throughout the journey, the teleoperated vehicles will be restocked with fresh Stop & Shop goods to ensure customers are provided with the best selection for purchase.

Love Coffee? Here's Another Reason to Care About Climate Change

At least 60 percent of wild coffee species are at risk of extinction, and climate change will make wild Arabica endangered, new research shows. Climate Change and deforestation are threatening most of the world's wild coffee species, including Arabica, whose domesticated cousin drips into most morning brews. With rising global temperatures already presenting risks to coffee farmers across the tropics, the findings of two studies published this week should serve as a warning to growers and drinkers everywhere, said Aaron P. Davis, a senior research leader at England's Royal Botanic Gardens and an author of the studies. "We should be concerned about the loss of any species for lots of reasons," Davis said, "but for coffee specifically, I think we should remember that the cup in front of us originally came from a wild source."

Global Commission Calls for a Food Revolution to Solve World’s Climate & Nutrition Problems

To stabilize climate and get people healthy, the world needs to overhaul its diet and agriculture systems, the EAT-Lancet commission says. That includes less meat. An ambitious report on the global food system from a commission convened by the prestigious medical journal The Lancet calls for a radical change in food production—or, as one of the authors put it: "Nothing less than a new global agricultural revolution." It's the latest research to emphasize that the futures of the climate and human health are deeply intertwined. In order to meaningfully reduce greenhouse gas emissions and stabilize the climate, the world needs a "comprehensive shift" in its diet, the authors say. "The dominant diets that the world has been producing and eating for the past 50 years are no longer nutritionally optimal, are a major contributor to climate change, and are accelerating erosion of natural biodiversity," The Lancet's editors write in a commentary accompanying the report, released Wednesday.

The Debate Is Over: The Oceans Are in Hot, Hot Water

The Earth’s surface is 70 percent water, but even that underestimates how vital ocean health is to our planet’s ability to maintain life. Recent results from scientists around the world only further confirm that our waterworld is in serious danger. Last week, a bombshell study confirmed that the oceans are warming 40 percent faster than many scientists had previously estimated. The finding partially resolved a long-running debate between climate modelers and oceanographers. By measuring the oceans more directly, scientists again came to a now-familiar conclusion: Yes, things really are as bad as we feared. The ocean stores more than 90 percent of all excess heat energy due to the buildup of greenhouse gases in the atmosphere. From the standpoint of heat, global warming is almost entirely a story of how rapidly the oceans are changing. Warming oceans work to melt polar ice, of course, thereby raising sea levels. But hotter oceans change how the atmosphere works, too. More heat energy in the oceans means more heat energy is available for extreme weather: Downpours of rainfall are happening more often, hurricanes are shifting in frequency and growing in intensity, freak ocean heat waves are spilling over into temperature records on land. Melting Arctic and Antarctic sea ice is also increasing wave height, which is accelerating coastal erosion — worsening the effects of sea-level rise. The now-inevitable loss of nearly all coral reefs — home to a quarter of the ocean’s biodiversity — is the most charismatic of the impacts. The changes[…] -
